ELECTRICAL CHARACTERISTICS
Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Response is tested in production at discrete frequencies f
0.5, 0.8 and 0.9 times f
Note 3: Relative to gain at 0.1f
Note 4: All digital inputs driven rail-to-rail. When driving digital inputs with
0V and 5V levels, the shutdown current will increase to 3.5mA (typ).

Note 5: Each digital input includes a small positive or negative current
source to float the CMOS input to V
The table shows the current due to this source when the input is driven at
the supply voltage opposite from the float potential. Pins CS/HOLD, F3, F2,
F0 and G3 to G0 float to the V
voltage. See “Floatable Digital Inputs” in Applications Information section.
